I am a FERS retiree and think it is quite obvious what he is saying. He is saying that it takes FERS, Social Security Supplement, and TSP to equate to a single CSRS annuity. The TSP funds that a CSRS retiree has is play money. If you wanted to equate a CSRS having to invest like a FERS person, then a CSRS would have to be willing to invest and take risk on about one third of their annuity from CSRS.
This is true. Some FERS folks need to be more risk averse due to their personal situation. I know I am.
I missed being CSRS by 4 months and am now early retired (Fed LEO). I have a considerable stash in my TSP but have been 100% G since April 2007. I draw monthly life expectancy payments off of my account and will have to do so till age 59.5
I was not always so conservatively invested in my TSP. I moved my funds to the G Fund in 2007 due to
A. Getting close to retirement
B. Getting nervous about all the subprime news I was hearing back then
Due to my moving all funds to G in 2007, I was fortunate enough to be spared the downturn of 2008. I recognize, however, that at some point I do need to return to an allocation that provides opportunity for greater returns in order to keep up with and/or beat inflation. I would like to make a move with my TSP monies to diversify a bit, but am personally not comfortable enough that there isn't another "black swan" event on the horizon to do so just yet. (Needless to say I don't visit TSP Talk much anymore for TSP allocation tips.)
To the OP, all I can say is: "you puts your money in, & you takes your chances" - if you aren't comfortable with the risk of putting your money in, then ya should think about staying in the G.
If you feel someone else's investment advice led you astray - it's not their fault, but rather yours for taking the advice.
